incognito129 has asked for the wisdom of the Perl Monks concerning the following question:

One of the things I like about python, is that when a script exits cause of an error, it spits out a traceback. I'm wondering is there anyway of getting a perl script to do this as well?

    As I mentioned in the CB when you asked there, use Carp:

    $SIG{__DIE__}= sub { require Carp; Carp::confess(@_); };

    Also, you can use Carp::Always. Start your script like this:

    perl -MCarp::Always script.pl
    and it will print backtrace if program die.
